Pressure oxidation - Wikipedia

Pressure Oxidation is a process for extracting gold from refractory ore. The most common The pressure oxidation process is used to prepare such ores for conventional gold extraction processes such as cyanidation. It is performed in an autoclave at high pressure and temperature, where high-purity oxygen mixes with a
